IMPROVEMENT IN UNIONS OR JOINTS FOR PIPES.

Specificationforming part of Letters Patent No. 198,818, dated January 1, 1878; application iiled Y November 19, 1877.

`To all whom it may concern:

-l tain new and useful Improvements in Unions or Joints for Pipes; and I do hereby declare lthat the following is a full, clear, and exact description thereof7 that will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this speciication.

This invention consists in making a union or joint for pipes, so that they can be readily applied and adjusted; and the improvements consistvin the employment of a nut having a rim or ilange at one end. 0n the face of this flange is a projection, which enters a corresponding recess formed in a Iiange of another nut. Upon both nuts is placed a loose rim or flange, having a series of holes for the insertion of bolts or pins. The two nuts are screwed or otherwise secured onto the ends of the pipes to be joined, `and are then placed together, and fastened by bolts passing through both the loose flanges. p

This invention will be better understood by reference lto the accompanying sheet of drawings, whereiny Figure l represents an oblique view of my improved union or joint, and Fig. 2, a section of same.

A is a nut, which is screwed or otherwise fastened onto the end of a pipe intended to be joined, and B is a tapered projection, which fits into a corresponding recess formed :in `another nut, O. D are loose anges'placed upon each nut, so that the two nuts can be drawn together by the bolts E, thereby making a perfectly tight joint vwithout the aid of packing.

It will be seen by any person at all conversant with mechanics that a good joint may also be made by letting the projection B fit loosely in the recess ofthe nut C, and an india-rubber ring or other packing, a, placed between the faces of the two nuts, as shown in Fig. 3. A

I claim as my invention- The loose angesD, in combination with nuts A, for the purposes herein shown and described. y

'Initestimony that I claim the foregoing I have hereunto" set my hand this 4th day of September, 1877.

JOSEPH SHAW.
